Give a signal with your hand when greeted during prayer

This hadith teaches us that when we are in the middle of prayer, it is important to remain focused on our worship and not be distracted by external conversations or greetings. Instead of replying to the greeting verbally, we should give a signal with our hand as a sign of acknowledgement. This hadith also emphasizes the importance of prayer in Islam and how it should be respected as an act of worship. It is important for Muslims to remember that prayer is an opportunity for us to connect with Allah and therefore should not be taken lightly or interrupted by other activities.
